In the hydrothermal treatment, grain size, particle morphology, crystalline phase, and surface chemistry can be controlled via processing variables such as sol composition, pH, reaction temperature and pressure, aging time, and nature of solvent and additive.
Results and discussion The crystalline structures of sol-gel (SG) and hydrothermal (HY) titania are investigated by means of XRD analysis and shown in Table 1.
It appears that the structure of SG TiO2 changes in consequence of the temperature while the crystalline phase of HY TiO2 is anatase independently of the thermal treatment.
The mild hydrothermal synthesis would be capable of yielding a more well-defined structure with less surface impurities/defects if appropriate setup is employed to ensure complete sol-gel reaction and crystallization.

The above results indicate that the structure P-O-Si has not been formed between HAP and the silane molecules in aqueous medium, which is quietly different from the situation in organic medium such as toluent.
All the peaks above do not exist in HAP particle, which suggests that the structures of the modified HAP particle contain parts of the silane molecule.
It is well known that the Si-O-Si structure was formed by condensation reaction between Si-OH groups produced from the silane hydrolysis by H2O molecules absorbed on the surface of HAP.

Magnetite or ferrous ferrite (FeO.Fe2O3 or Fe3O4) is an iron oxide which has an inverse spinel structure with Fe(III) ions distributed randomly between octahedral and tetrahedral sites, and Fe(II) ions in octahedral sites [6].
The characteristic peaks of both MHT-H and MHT-NH composites indicate that both of them have a layered structure with basal spacing 7.91 Å and 8.03 Å which indicated NO3- anion in interlayer [13].
The result of XRD pattern for CMHT-H and CMHT-NH shows the presence of destruction of hydrotalcite structure because of dehydration and decomposition of the anions and exhibit a transformation from the hydrotalcite into a mixed oxide with MgO like structure or rather MgO–Al2O3 solid solution MHT-H composite has a BET specific surface area (SBET) of 63.264 m²/g, larger than MHT-NH composite (2.448 m²/g).
The calcination process exhibit a transformation from the hydrotalcite into a mixed oxide with MgO like structure or rather MgO–Al2O3 solid solution and decreasing saturation magnetization.

Organisms are capable to fabricate very complicated hierarchical structures with superior physical and chemical characteristics.
In the depositions, a large number of flower-shaped structures were observed in the image of the down-side of the product (Fig. 1a).
When 10 ml of 50 mM hexadecyltrinethyl ammonium bromide in n-Hexane was injected on the saturated Ca(OH)2 solution, flower-shaped structure could not be gotten.
The products showed tilted hexahedron stacked structures as showed in Figure 3.

In addition, fibril structure was observed in the PLLA/PLA microsphere blend.
This fibril structure can be related to increase ductility of the sample [7].
Fibril structure is observed in PLLA/PLA microsphere blend microstructure indicating the ductility of PLLA/PLA microsphere blend.

Introduction As is well known, metal oxide particles are widely used in various applications such as electronics, optics, industrial ceramics, biochemistry and pharmaceutical industry owing to their novel structures and the corresponding unique properties.
Therefore, the studies of the preparations, structures, properties and applications of these metal oxide nanoparticles have gained much attention in the world [1-5].
From characteristic peaks in this XRD image, CeO2 can be indexed as face centered cubic structure, which corresponds to the PDF card 81-0792.

Introduction Casein is an important component of dairy products, it mainly comprises 4 phosphorylated monomers (αS1-casein, αS2-casein, β-casein, κ-casein) which form micelle-like structure in aggregate style.
Because the structure of casein is extremely complex, the casein has many unique physicochemical properties and biological functions.
Dynamic light scattering as an important means of studying polymer molecular structure can directly determine the parameters of macromolecules in solution such as diffusion coefficient, particle size and distribution, and has the advantages of no interference with the sample, informative, simple and fast, it also has played an important role in the characterization of protein structure [2], analysis of aggregate process [3] and interaction [4,5].

The melts solidify in the form of single phase solid solutions, with fcc crystal structure (inherited from the Ag host).
Consequently, the reason of varying slope Θ(T) is the consequence of the change in bulk electronic structure, caused by the host metal replacement.
